Monodactylus argenteus

The Silver Moony, also known as the Mono Angelfish, is a beautiful and incredibly active fish that brings a lot of energy to an aquarium. Its body is shaped like a diamond and has a brilliant silver color, making it a striking centerpiece. These are social creatures that must be kept in groups; a lone Moony will become stressed and unhealthy. To be happy, they need to be with several of their own kind, which allows them to feel safe and display their natural swimming behaviors.

One of the most unique things about Silver Moonies is their changing water needs. When they are young, they live in water that is only slightly salty, but as they grow into adults, they need to live in a full saltwater marine environment. This gradual change can be challenging, so they are best suited for keepers with some experience. They are not picky eaters and will eagerly accept a variety of fish foods, including flakes, pellets, and vegetables. Because they are omnivores, they are known to nibble on and eat live aquarium plants. They are also powerful swimmers and can jump out of the water, so a secure tank lid is absolutely necessary.
